Parents of Peachtree Park Pediatrics,

We continually strive to provide you with the most up to date information on the COVID-19 pandemic. Read on for the latest vaccine updates, Delta variant concerns, mask-wearing recommendations and more.


Delta Variant Now Dominant in U.S.

The CDC indicates that the more contagious Delta variant accounted for more than 50% of U.S. COVID cases in late June and early July.

“A CDC spokesperson told POLITICO surveillance data indicated the Delta variant jumped from 30.4 percent of cases for the two-week period ending June 19 to 51.7 percent between June 20 and July 3.”


Cases Up in Half of U.S. States

“COVID-19 cases are trending upward in nearly half of all states in the U.S., according to a new analysis.

Vaccine May be Less Effective Against Delta Variant

The Hill reports that “a study conducted in Israel found that the Pfizer COVID-19 vaccine is somewhat less effective against the more infectious delta variant, though it was still found to be effective at preventing severe illness.”

While vaccine protection against any illness was 64% for the Delta variant, the vaccine remained effective preventing against severe disease at 94%.


Vaccination in the U.S. Saved 280K Lives

Fierce Healthcare reports that “the quick rollout of the COVID-19 vaccine in the U.S. saved an estimated 279,000 lives and prevented 1.25 million hospitalizations, a new study finds.”


Are Booster Doses of Vaccine Needed?

Pfizer has announced that it plans “to seek authorization from the Food and Drug Administration (FDA) for a third dose of their COVID-19 vaccine, saying it would provide even stronger protection.”

The company said they have seen ‘encouraging data’ from an ongoing trial of the booster shot, adding that it provides levels of neutralizing antibodies five to 10 times higher, when administered six months after the second dose. The company plans to submit data ‘in the coming weeks.’”

In response, the FDA and CDC stated that “Americans who have been fully vaccinated do not need a booster shot at this time,” adding that they are engaged in a “science-based, rigorous process,” to determine if one will be needed.

Some other countries are giving a 3rd dose of vaccine to certain people with weakened immune systems, as the New York Times discusses in a recent report.


CDC Says Masks are Not Needed in Classroom if Vaccinated

The CDC relaxed its COVID-19 guidelines, indicating that “vaccinated teachers and students don’t need to wear masks inside school buildings.”

The CDC continues to recommend that “anyone over the age of 2 who isn’t fully vaccinated – students, teachers and staff – continue to wear masks indoors and to try to keep 3 feet of distance.”


Why is the Delta Variant Able to Elude the Immune System?

The NY Times writes that “the Delta variant of the coronavirus can evade antibodies that target certain parts of the virus, according to a new study.”

“The study found that Delta was barely sensitive to one dose of vaccine, confirming previous research that suggested that the variant can partly evade the immune system.

The researchers looked at blood samples from 103 people who had been infected with the coronavirus. Delta was much less sensitive than Alpha to samples from unvaccinated people in this group, the study found.

One dose of vaccine significantly boosted the sensitivity, suggesting that people who have recovered from Covid-19 still need to be vaccinated to fend off some variants.”

Mask Wearing at the Gym is Safe

HealthDay reports that “wearing a mask while you exercise may be uncomfortable, but a new study should reassure gym-goers that it poses no actual health risks.”

Unvaccinated individuals should continue to wear a mask during indoor exercise, while vaccinated individuals can wear a mask if desired, knowing that the mask can be worn safely.


Vaccines Don’t Enter Breast Milk

HealthDay reports on a recent study showing that the mRNA of COVID vaccines was not found in breastmilk of vaccinated mothers.

“The researchers say their findings ‘provide important early evidence to strengthen current recommendations that vaccine-related mRNA is not transferred to the infant,’ so moms don’t have to choose between COVID vaccination and breastfeeding.”


We encourage everyone to continue to use good hand hygiene and practice social distancing as much as possible. Please contact our office with any further questions or concerns.
